.ment at their abutting ends by internal sleeves, are driven or sunkeninto the ground, a cluster of iron or steel reinforcing rods placedtherein, and the pile casing then filled with cement or concrete so asto unite the casing sections, alining sleeves and reinforcing rodstogether and to the concrete l zo lling to make the complete pile.

My invention consists mainly in makin the internal alining sleeveselongated, wit guiding and holdin tubes or semi-tubes, for thereinforcing ro s, of a length equal to that of the respective sleeve orsuicient to allow for' considerable variations in the length of thesections of the reinforcing rods, which are made in lengthssubstantially equal to the respective tubular sections of the casing, sothat when the lowest casing section is sunken into the ground, and thelowest sections of the reinforcing rods and the alining sleeve 'placedthereon, the upper ends of the rod sections will all rest within therespective guiding tubes of the alining sleeve in spite of variations inthe lengths of rods. Likewise when the neXt casing section is drivenhome and the corresponding rod sections are placed therein with theirlower ends in the guiding tubes of the first alining sleeve, the upperends of said rods will also all be within the guiding tubes of the nextalining sleeve, all

as will be hereafter more fully described.

In order that my invention may be fully understood I shall firstdescribe in detail the mode in which I carry m invention into practiceand then distincty claim the invention.

Reference is to be had to the accompanying drawings forming part of thisspecification,. in which like parts are designated byA the same numbers-in all the figures. y

Figure 1 is a sectional side elevatlon of a reinforced-incased concretepipe embodying my invention. Fig. 2 is an enlarged plan view of thecombined alining sleeve and rod holder of the same. Fig. 8 is a sideelevation partly 1n section of the combined alining sleeve and rodholder. I In the drawings 10, 11 are the tubular metalllc sections,formlng the casing of the pile; -12'is the driving cap preferably usedfor recelving the blows of the pile driver; 13 is the driving shoeformed with a neck le to lit tightly within the lower end of the pllecasing; 15 1s one of the metallic internal sleeves for holding theabutting ends of the caslng sections in alinement, and 16 are thereinforcing rods, placed and held vertically apart within the pilecasing.

The concrete or cement filling is poured mto the pileA casing, after thecasing is driven home and the reinforcing rods are placed therein, tobind and unite the casing sections, alining sleeves, driving shoe, ifused, aud reinforcing rods together to form the complete pile.

Eciently, conveniently and economically to gulde and hold the verticalreinforcing rods 16 in position apart, I preferably cast on the interiorside wall of the hollow driving shoe 13, when one is used, inwardly andradially projecting-bosses 18 spaced peripherally around the shoe as thereinforcing rods 16 are to be spaced, and formed in their upper endswith vertical .sockets 19 to receive loosely the lowerends of theseveral reinforcing rods 16, after the pile casin is driven home. To thesame end, I preferaly 'cast the alining sleeve 15 with inwardly and`radially projecting bosses 20 formed with vertical guiding tubes orsemi-tubes 21, spaced peripherally around the sleeve 15 as the verticalreinforcing rods 16 are to be spaced, to receive and hold said rods intheir proper-relative positions within the casing. l

The vertical reinforcing rods 16 are made in sections substantiallyequal in length to the respective casin sections, so that the ends ofthe rod sections will terminate and rest in the guiding tubes 21 of therespective alining sleves 15; but as the rod sections will in practicevary considerably from this length, it is essential that the tubes 21 beelongated the full length of the elongated alining sleeve 15 with whichthey are formed or at least a substantial part of said length, so that,irrespective of said variations in length of the rod sections, theirends will always extend into and be confined in the elongated guidingtubes 21.

It is evident that in sinking the casing sections, and introducingtherein the alining sleeves 15, the rod guiding tubes 21 therein must beplaced in axial alinelnent with the rod sockets 19 in the driving shoeand with the rod guiding tubes 2 1 in the other alining sleeves.

To hold the alining sleeve 15 in position in the abutting end portionsof the casing sections 10, 11, I may use any suitable means, such asindentations 22 in the casing sections above and below the aliningsleeve 15, as shown in Fig. 4, and claimed in my prior United StatesLetters Patent, dated May 31, 1910, No. 959,546. In Figs. 1, 2 and 3,however, I have shown the alining sleeve 15 cast with an integralperipheral ring 23 around its middle, by preference slightly dovetail insection, to come betiveen and register exteriorly with the abutting endsof the casing sections 10, 11, to receive t-lie end 'thrust thereof andserve as a stop to hold the sleeve against endwise displacement Withinthe abutting ends of the sections 10 and 11, as shown in Fig. 1. In thisinstance, I continue the medial ring 23 inward to the interior of therod guiding tubes 21, to serve as bearings for the respective ends ofthe reinforcing rods. l

It will be evident that, When the diaphragm portion 2li extending acrossthe guiding tubes 21 is omitted, then the lower end of each rod section1G Will rest,Wit-hin the respective guiding tube 21, upon the upper endof the rod section below it, and the described elongation of the guidingtubes will insure the meeting of the superposed rod sections Within theguiding tube in spite of the variations in the lengths of the rodsections.

The integral formation of the alming sleeve with the lnteriorrod-holding bosses forms an extremely simple, economical, effective andconvenient means for guiding and holding the reinforcing rods in theirallot-ted positions, and the rod holding bosses in addition cooperateeffectively with the concrete filling, tubular sections, sleeves andreinforcing rods to bind the Whole coinposite pile together and form apile of great strength and durability.

Having thus described my invention and the mode in which I carry.thesame into practice, I claim:

1. In reinforced incased concrete piling, the combination Wit-h thetubular metallic casing sections, of an elongated alining sleeve fittedWithin the abutting ends of the casing sections and formed interiorlyWith elongated longitudinal guiding tubes for reinforcing rods toconfine the meeting ends of rod sections of varying length, reinforcingrod sections of a length substantially equal to that of thecorresponding casing sections having their adjacent ends confined Withinthe respective guiding tubes and a filling of concrete to unite theWhole together.

2. The elongated alining sleeve for joining the abutting ends of themetallic casing sections together formed interiorly with elongatedlongitudinal guiding and conning tubes for the varying meeting ends ofvertical reinforcing rods, substantially as described.
